The figure of 249 therms is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.68 with the daily hot-water draw that the DOE test assigns to the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure is natural gas only and holds only at that test draw. Against the 414 models registered as a gas tank at the high draw pattern, this model sits 11 therms below the class median of 260 therms. It ranks 164th lowest in energy use among 414, which places it in the second-lowest quarter of its class.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 103 gallons for this model, and the rated volume is 46 gallons. The registry data do not say whether that matches your household's real peak demand. A household whose use differs from the test draw should not expect 249 therms, because the figure applies only to the high draw pattern. It also applies only to natural gas; energy use on any other fuel is not available here. The selector by fuel, space and size covers those other cases.

The running cost is not written here. It depends on your state average residential gas price applied to 249 therms, and the price is not in the registry data. The cost calculator on your own ZIP does that multiplication, and the page on how the annual cost is calculated sets out the method. The gap of 11 therms from the class median of 260 therms is a difference in gas use, so its value in money depends on your rate. A modeled installed-cost range is shown in its own block with its source and date; it is not a quote. To compare this model with another of its class, find a same-class replacement by model number.
